Description

Adjustable spanner

Technical Field

The invention relates to the technical field of hand tools, in particular to an adjustable wrench.

Background

A monkey wrench, a wrench for short, is a tool used for fastening and loosening nuts. In industrial production, a wrench is one of the indispensable tools, and especially, a monkey wrench is widely popular due to its flexible operation. The adjustable wrench generally comprises a handle, a movable jaw and a fixing part, wherein the fixing part is connected with the handle, a groove is formed in the fixing part, the movable jaw is arranged in the groove, a plurality of teeth are arranged below the movable jaw, and the purpose of adapting to different bolts is achieved by adjusting the relative distance between the adjustable jaw and the fixing part through an adjuster. At present, when a wrench is used for fastening or loosening bolts and nuts, the problems of slipping, slipping and the like of the bolts and the nuts due to long-term use are frequently encountered, the movable end and the fixed end of the conventional adjustable wrench are linear, and the bolts and the nuts are often difficult to fasten or loosen efficiently in time due to the slipping situation.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide the adjustable wrench which is simple in structure, convenient to use and capable of saving physical strength.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides an adjustable spanner, includes the body, the one end of body the stiff end has, the body on be located the lateral part of stiff end be equipped with the spout, the spout on swing joint have a expansion end, be provided with the hand wheel on the spout, the other end of body be the handle, the internal surface of stiff end is provided with right contained angle, the internal surface of expansion end is provided with left contained angle, the right contained angle of stiff end becomes axial symmetry with the left contained angle of expansion end.

The right included angle of the inner surface of the fixed end is 90-150 degrees.

Further, it is preferable that the right included angle of the inner surface of the fixed end is 120 °.

Further, the handle is cylindrical.

The outer surface of the handle is provided with a rubber sheath.

The invention adopts the technical scheme that the method has the beneficial effects that: the adjustable wrench is simple in structure and convenient to use, the right included angle is formed in the inner surface of the fixed end, the left included angle is formed in the inner surface of the movable end, the right included angle of the fixed end and the left included angle of the movable end are in axial symmetry, the contact area between the wrench and the bolt and the nut is increased, the bolt and the nut are wrapped between the movable end and the fixed end of the wrench, the problem that the bolt, the nut and the wrench slip can be effectively solved, and the adjustable wrench can fasten or loosen hexagonal or square bolts and nuts and can fasten or loosen round bolts and nuts.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the handle comprises a body, a handle 2, a fixed end 3, a movable end 4, a hand wheel 5, a right included angle 61 and a left included angle 62.

Detailed Description

The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention in any way.

As shown in fig. 1, in order to achieve the above object, the technical solution of the present invention is: the utility model provides an adjustable spanner, includes body 1, the one end of body 1 stiff end 3 has, body 1 on lie in the lateral part of stiff end 3 be equipped with the spout, the spout on swing joint have expansion end 4, be provided with hand wheel 5 on the spout, the other end of body 1 be handle 2, its characterized in that: the internal surface of stiff end 3 is provided with right contained angle 61, the internal surface of expansion end 4 is provided with left contained angle 62, the right contained angle 61 of stiff end 3 becomes axial symmetry with the left contained angle 62 of expansion end 4.

The right included angle 61 of the inner surface of the fixed end 3 is 90-150 degrees.

Further, preferably, the right included angle 61 of the inner surface of the fixed end 3 is 120 °, and the left included angle 62 of the movable end 4 is 120 ° because it is axisymmetric with the right included angle.

Handle 2 is cylindrical, compares than the rectangle handle, has increased the atress area, uses more comfortablely, conveniently exerts external force.

Further, a rubber sheath is arranged on the outer surface of the handle 2.

When the product is used, the inner surface of the fixed end 3 is provided with the right included angle 61, the inner surface of the movable end 4 is provided with the left included angle 62, the right included angle 61 of the fixed end 3 and the left included angle 62 of the movable end 4 are in axial symmetry, the unit contact area of a wrench and a bolt and a nut is increased, the bolt and the nut are wrapped between the movable end 4 and the fixed end 3 of the wrench, the problem of slippage between the bolt and the wrench can be effectively solved, and the adjustable wrench can fasten or loosen both hexagonal or square bolts and nuts and round bolts and nuts.

The foregoing shows and describes the general principles and features of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
